Caterpillar original 230-3255 Fuel Injector 250-1304 for Caterpillar C3500 3508 3512 3516, Replacement for OEM 246-1854, 392-0206 Diesel Fuel Injector original new injector

Engineered specifically for the Caterpillar 3512B engine platform, the CAT 230-3255 fuel injector is a precision-manufactured diesel injection component built to strict OEM specifications. Designed for the 51.8-liter V12 four-stroke diesel with electronic unit injection, turbocharging, and aftercooling, it supports 3512B, 3512B-HD, Marine, Industrial, Generator, Offshore, and Oilfield engine configurations operating under extreme heavy-duty conditions.

As a critical element of the fuel injection system, injector performance directly determines power output, fuel economy, emissions, combustion stability, cold-start capability, and overall engine longevity. During each injection cycle, fuel pressure builds to the calibrated nozzle opening pressure, the needle lifts, and diesel is atomized through precision-engineered nozzle orifices into microscopic droplets for complete combustion. The result is maximized thermal efficiency across the operating range—improved fuel economy, lower particulate emissions and smoke, enhanced engine responsiveness, and extended service life from industrial-grade, wear-resistant metallurgy.

This injector cross-references OEM and interchange numbers 10R-7228 (10R7228), 0R-3306 (0R3306), 234-3255 (2343255), and 235-3255 (2353255), simplifying global sourcing and inventory management. Typical installations include generator sets, diesel power plants, mining and heavy-haul trucks, marine vessels, commercial ships, tugboats, offshore equipment, oilfield machinery, industrial power systems, construction machinery, and emergency generator systems. With globally recognized OEM and aftermarket availability, the 230-3255 helps fleet operators and maintenance teams reduce downtime and control long-term maintenance costs.
